lMPROVEMENT IN SLEEVE AND COLLAR BUTTONS.

Specification forming part of Letters Patent No. 219,325, dated September 1879; application filed July 11, 1879.

To all whom it may concern:

Be it known that I, RIOKERSON M. TRIPP,

of the city, county, and State of New York,

have invented certain new and useful Iin provements in Sleeve and Collar Buttons, of which the following is a'specification.

In the accompanying drawings, Figures 1 and 2 represent, respectively, a side view of the shank and detachable head portion of my improved sleeve and collar button. Figs. 3 and 4 are, respectively, a top view and a vertical transverse section of the same on line as as, Fig. 3. Figs. 5 and 6 are detail views of the shank-locking catches or jaws. Fig. 7 is a bottom view of an oblong sleeve-button, and Fig. 8 a side view of the oblong shank of the same.

Similar letters of reference indicate corresponding parts. K

This invention has reference to improvements. in sleeve and collar buttons of that class in which the head or face portion may be detached from and replaced on the shank, for the more convenient removing or putting on of the sleeves and collars; and the invention consists of a solid shank, which is locked by means of spring catches or jaws to the head or face portion, and steadied thereon by a socket-recess of the top plate of the guidebox and a collar of the shank.

Referring to the drawings, Arepresents the shank portion, and B the head or face portion of my improved sleeve and collar button.

The shank A is made solid, in place of being hollow or tubular for the reception of the fixed shank-post of the face portion, as has been commonly the case in buttons of this clashs, and the fixed post is entirely dispensed wit The head a of the shank A is tapering or rounded off, and provided, in round shanks, with an annular recess, b, back of the head, as in Fig. 1, or, in case of oblong shanks, such as used for sleeve-buttons of oblong shape, with recesses 11 at both sides, as shown in Fig. 8.

Back of the recess or recesses the shank is provided with a somewhat larger collar, d, as shown in Figs. 1 and 8.

The face portion B is arranged with a guide box or casing, B, which is formed of a top and The jaws O are provided with studs or pushers e, which extend through side openings of the face portion B to the outside.

The jaws O are made of the shape shown respectively in Figs. 5 and 6, with a large central opening that has at one side the arc-shaped and tapering jaw.

One of the jaws (l is narrower than the other so as to be inserted through the opening into the other jaw. Both jaws O are provided about midway of their length with offsets f, by which the front part of each jaw is slightly raised, so that when the front part of the narrower jaw has been inserted into the wider jaw it will slide along the lower part of the latter, while the raised front part of the wider jaw slides along the lower part of the narrower jaw, as shown in the cross-section in Fig. 4.

The narrower jaw G has projecting side shoulders, f which form contact with the offsets of the wider jaw by the action of the connecting-spring f which is so connected tothe jaws that they are forced in opposite di= rections.

By pressing the pushers inwardly the jaws slide over each other until they open sufficiently to release the shank. Their inter meshing portions guide each other without re quiring any other means of guiding.

When the face portion B is placed on the shank A the tapering head of the latter enters between the jaws and spreads them apart un til the head passes back of the same,when they lock the shank back of the head.

For the purpose of producing a steady connection of the shank and face portion the top plate of the guide-box B is provided with a socket or socket-recess, g, for the head of the shank. This socket g, in connection with the enlarged collar 61, that bears on the bottom plate of the guide-box B, holds the shank in rigid position without any wabbling. 1 This is an essential feature of my improved button, as I obtain thereby not only a simpler con .struction, dispensing with the fixed shank= post of the face portion, but 1 am also enabled to use the same construction with equal facility both for round and oblong buttons-a outer and a head-retaining socket in the inpoint that has not been accomplished heretoner plate of the same, and with locking springfore in this line of goods. jaws G, substantially as specified.

Having thus described myinvention,Iclai1n In testimony that I claim the foregoing as as new and desire to secure by Letters Patmy invention I have signed my name in present ence of twowitnesses this 7th day of July, 1879.
